i have an issue with the python code i took from the arcgis help
im trying to run it but without any succes i modify to the durectory and the rasters i work with but it keeps telling me that i have error 000735
HERE"S THE PYTHON CODE
# Name: IsoClusterUnsupervisedClassification_Ex_02.py
# Description: Uses an isodata clustering algorithm to determine the
# characteristics of the natural groupings of cells in multidimensional
# attribute space and stores the results in an output ASCII signature file.
# Requirements: Spatial Analyst Extension
# Author: ESRI
# Import system modules
import arcpy
import sys
from arcpy import env
from arcpy.sa import *
# Set environment settings
env.workspace = "e:\Users\profiles\sjmeel77\Desktop\arcgis_jmeel"
# Set local variables
inRaster = sys.argv[1]
classes = 8
minMembers = 50
sampInterval = 15
# Check out the ArcGIS Spatial Analyst extension license
arcpy.CheckOutExtension("Spatial")
# Execute IsoCluster
outUnsupervised = IsoClusterUnsupervisedClassification(inRaster, classes, minMembers, sampInterval)
outUnsupervised.save("e:\Users\profiles\sjmeel77\Desktop\arcgis_jmeel\iso_clustre.pyoutunsup01.tif")
and heres the error that appears after the process
